Ekart Logistics — My parcel has not been delivered yet

Dear Ekart team. I am really disappointed with your service. It's been more than 10 days i booked a parcel from Kolkata for Mumbai but it has not been delivered yet. The delivery boy did not even tried to contact the person. They are marking falsely.
The following is the tracking number - BGSC[protected]. I have tried to contact the support team for several times but not getting any response. Kindly look into the matter and do the needful at the earliest.
